The Foway7500-16FS series is a 16-port 10-gigabit Ethernet Fibre Channel switch, with 16 10-gigabit SFP+ optical ports (1000M or 10G SFP+ optical modules optional) connected to it and supports hot-swappable universal SFP/SFP+ optical modules. The EqualLogic FS7500 hardware configuration consists of two FS7500 Controller units and one FS7500 Backup Power Supply (BPS) unit. Where switches simply block or pass optical signals on individual or multiple channels, multiplexers route multiple channels out to a single fiber optic cable. Page 2 Copyright 2011 Dell, Inc.
